Only a partial solution, I know, but for anything that inherits from 
Qt's QObject class (and properly uses the Q_OBJECT macro in its 
header), you can use the following function as a poor man's 
dynamic_cast:

bool QObject::inherits( const char * className )

Won't be useful in parts of the code that don't use Qt much, though.
